Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 27 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2026-27776, organizations should first verify whether the IM-LogicDesigner module is deployed in their intra-mart Accel Platform environment. If deployed, immediate steps should include: 1) Applying any available patches or updates from NTT DATA INTRAMART Corporation as soon as they are released. 2) If patches are not yet available, restrict access to the IM-LogicDesigner module to trusted administrators only and enforce strict access controls. 3) Implement file integrity monitoring and restrict the import of files to only those from verified, trusted sources. 4) Employ network segmentation to isolate the platform from less trusted network zones to reduce exposure. 5) Monitor logs and system behavior for unusual activities that may indicate exploitation attempts. 6) Educate administrators about the risks of importing untrusted files and enforce policies to prevent importing files from unverified origins. 7) Consider deploying runtime application self-protection (RASP) or endpoint detection and response (EDR) solutions to detect and block suspicious deserialization activities. These targeted steps go beyond generic advice by focusing on controlling the import process, limiting administrative exposure, and enhancing detection capabilities.

Description

IM-LogicDesigner module of intra-mart Accel Platform contains insecure deserialization issue. This can be exploited only when IM-LogicDesigner is deployed on the system. Arbitrary code may be executed when some crafted file is imported by a user with the administrative privilege.

Impact

The impact of CVE-2026-27776 is significant for organizations using the intra-mart Accel Platform with the IM-LogicDesigner module. Successful exploitation can result in arbitrary code execution with administrative privileges, leading to full system compromise. This can cause unauthorized access to sensitive data, modification or deletion of critical information, disruption of business operations, and potential lateral movement within the network. Given the administrative privilege requirement, the threat is more severe in environments where multiple users have elevated access or where administrative credentials are not tightly controlled. The vulnerability could also be leveraged as a foothold for deploying ransomware, data exfiltration, or further attacks against the organization's infrastructure. Since the platform is used in enterprise environments, the potential for widespread operational disruption and data loss is high. Organizations that fail to address this vulnerability risk severe confidentiality, integrity, and availability impacts.
